OBJECTIVE:To observe clinical efficacy and safety of Bushen sanhan tongluo decoction combined with moxi-bustion and celecoxib in the treatment of knee osteoarthritis (KOA). METHODS:A total of 70 KOA patients were selected from Chongqing Kanghua Hospital during May 2014-Dec. 2015,and then divided into observation group and control group ac-cording to odd and even number,with 35 cases in each group. Control group was given Celecoxib capsule 0.2 g,qd;observa-tion group was additionally given Bushen sanhan tongluo decoction(one dose a day,300 mL,decocted with water,taking it 3 times in the morning,noon and night)and moxibustion. A treatment course lasted for 4 weeks,and both received 2 courses of treatment. Clinical efficacies as well as TCM syndrome score,VAS score,WOMAC score,lab indexes,joint condition be-fore and after treatment,the occurrence of ADR were compared between 2 groups. RESULTS:Total response rate of observa-tion group (85.71％) was significantly higher than control group (68.57％),with statistical significance (P<0.05). Before treatment,there was no statistical significance in above indexes between 2 groups (P>0.05). After treatment,TCM syn-drome score,VAS score,WOMAC score,erythrocyte sedimentation rate,CRP level and knee swelling score of 2 groups were decreased significantly,compared to before treatment;those indexes of observation group were significantly lower than those of control group,with statistical significance(P<0.05). There was no statistical significance in the number of bone fric-ative joint between 2 groups before and after treatment (P>0.05). There was no statistical significance in the incidence of ADR (5.71％ vs. 2.86％) between 2 groups (P>0.05). CONCLUSIONS:Bushen sanhan tongluo decoction combined with moxibustion and celecoxib can improve clinical symptoms,relieve joint pain,joint inflammation and swelling of KOA pa-tients with good safety.

Objective To evaluate the value of DWI in assessing the biological characteristics of breast invasive ductal carcinoma (IDC).Methods Eighty-seven IDC lesions confirmed by postoperative pathology were involved in this retrospective study.The ADC values of IDC were compared among different lymph node status,grades,and molecular subtype.The correlations of ADC value and lymph node status,grades,and molecular subtype were evaluated.Results The ADC value of IDC with positive lymph node was lower than that with negative lymph node (P=0.035),and the ADC value of the high grade IDC was lower than those of medium grade IDC and low grade IDC (P=0.021,0.002).There was no significant difference of ADC value between different molecular subtypes.There was low negative correlation of ADC value with grades (r.s =-0.357,P 0.001) and week negative correlation of ADC value lymph node status and nolecular subtype (rs =-0.227,P=0.034;rs-0.093,P＜0.001).Conclusion DWI can provide useful information in evaluating the biological characteristics of IDC.

OBJECTIVETo observe the effect of hepatitis virus B on the detection rate of core antigen of hepatitis virus C in sera of chronic hepatitis C patients.

METHODHCVcAg and HCV RNA in sera were detected in 88 patients with chronic hepatitis C and 62 patients co-infected with HCV and HBV. At the same time, HBV DNA and HBeAg in sera were detected in 62 patients infected with HCV and HBV. Then we analyzed the correlation between HCVcAg and HBeAg/HBV DNA. The detection rates of HCVcAg in 88 patients with chronic hepatitis C and 62 patients co-infected with HCV and HBV were 72.7% (64/88) and 38.7% (24/62), respectively (x2 = 17.358, P less than 0.01).

RESULTSThe detection rates of HCV RNA in 88 patients with chronic hepatitis C and 62 patients co-infected with HCV and HBV was 81.8% (72/88) and 53.2% (33/62)respectively (x2=20.110, P less than 0.01). In 62 patients infected with HCV and HBV, the detection rate of HCVcAg in HBeAg positive patients and HBeAg negative patients were 28.6% (12/42) and 60% (12/20), respectively (x2 = 7.547, P = 0.011). Moreover, the positive rates of HBV DNA in HBeAg positive patients and HBeAg negative patients were 42.9% (18/42) and 80% (16/20), respectively (P more than 0.05). The detection rates of HCVcAg in HBV DNA positive patients and HBV DNA negative patients were 39.1% (18/46) and 37.5% (6/16), respectively (x2 = 0.013, P = 0.908). Compared with the detection rates of HCVcAg in patients only infected with HCV, the detection rate of HCVcAg in HBeAg or HBV DNA negative patients infected with HCV and HBV were 60% (12/20) (x2 = 1.266, P = 0.261) and 37.5% (6/16) (x2 =7.635, P less than 0.01), respectively.

CONCLUSIONThe detection rate of HCVcAg in patients infected with HCV and HBV is relatively low. The reason is possibly that HBeAg inhibits duplication of HCV and decreases the expression of HCVcAg.

OBJECTIVETo evaluate the prognostic effects of neoadjuvant chemotherapy (NAC) in patients with local advanced gastric cancer.

METHODSWe retrospectively analyzed prognosis in 191 patients with advanced gastric cancer, of whom 71 were treated with NAC and 120 received surgery only between February 2007 and July 2013. Postoperative complication rate was recorded. Survival by clinicopathological features, pathological T and N stages, and histopathological tumor regression was retrospectively compared between the two groups.

RESULTSAccording to Response Evaluation Criteria in Solid Tumors, none of the 71 patients in the NAC followed by surgery group showed complete response, 36 showed partial response, 25 had stable disease, and 10 had progressive disease. The chemotherapy response rate was 50.7%; the disease control rate was 85.9%. Grade 3/4 adverse events were seen in less than 20% patients, with acceptable toxicities. No difference was found in the overall postoperative complication rates between the two groups (7 versus 22 cases, P=0.18). Median survival time was significantly different, at 54 months in the NAC combined with surgery group and 25 months in the surgery-only group (P=0.025).

CONCLUSIONIn patients with operable gastric adenocarcinomas, NAC can significantly improve overall survival without increasing surgical complications.

BACKGROUNDNifekalant may prevent atrial fibrillation (AF) and possibly be useful in treatment of atrial tachyarrhythmia in patients with severe heart failure. This study investigated the electophysiologic effect of nifekalant on the acute atrial remodeling in rapid atrial pacing (RAP) model of canine.

METHODSTwelve mongrel dogs subjected to rapid stimulation (400 beats/min) at left atrial appendage (LAA) for 24 hours, were randomized into the control group (rapid pacing only, n = 6) and the nifekalant group (intravenous nifekalant therapy immediately after RAP, n = 6). Atrial electrophysiological parameters were measured in right atrium, coronary sinus, LAA, posterior wall of left atrium (PWLA) and left superior pulmonary vein (LSPV), before and after the RAP.

RESULTSIn the control group, the effective refractory periods (ERP) were shortened greatly at all sites, paced dogs had substantially shorter ERPs in the high right atrium, LAA, and LSPV, but fewer changes in the PWLA, the coefficient variation of ERP (COV ERP) was increased significantly. After rapid atrial stimulation, the inducibility of AF increased significantly [induction number: pre-RAP vs post-RAP, 1.00 +/- 0.89 vs 8.17 +/- 2.79, P < 0.01; duration of AF: pre-RAP vs post-RAP, (450.34 +/- 362.59) ms vs (9975.77 +/- 4376.99) ms, P < 0.01]. In the nifekalant group, although the ERPs were prolonged at all sites compared with those in pre-RAP state, only the value at LSPV differed significantly from that in pre-RAP state [pre-RAP vs post-RAP, (102.50 +/- 5.24) ms vs (132.51 +/- 5.20) ms, P < 0.01]; the COV ERP did not change statistically in this group. The inducibility of AF slightly increased but insignificantly after pacing [induction number: pre-RAP vs post-RAP, 0.83 +/- 0.75 vs 1.67 +/- 0.82, P = 0.19; duration of AF: pre-RAP vs post-RAP, (378.67 +/- 317.88) ms vs (1124.08 +/- 1109.77) ms, P = 0.06]. Conduction time values did not alter significantly in either of the two groups after RAP.

CONCLUSIONSIn canine RAP model, nifekalant inhibited ERP shortening and ERP heterogeneity increasing, decreased AF induction. Nifekalant can reverse acute electrical remodeling effect in this model.

This study is to investigate the effect and mechanism of puerarin on DNA damage of HaCaT cells induced by UVB. Puerarin pre-treated cells were irradiated with UVB at 30 mJ x cm(-2). Twenty four hours after irradiation, DNA damage was detected by comet assay, ceramide was measured by thin layer chromatography and gas chromatography, intracellular free calcium ion was analyzed by flow cytometry, the phosphorylation level of p38 protein was examined by Western blotting method. Levels of DNA damage, ceramide, free calcium ion and p-p38 protein were elevated in UVB model cells. Contrary to the model group, all indicators above were reduced in all groups pre-treated by puerarin. Puerarin restrains the ceramide accumulation to block downstream p38 MAPK pathway and calcium ion rising, therefore reduces DNA damage in HaCaT cells induced by UVB.

Objective To find out the current thyroid volume of school children and its influencing factors in Chongqing.Methods Probability sampling method(PPS) was used to select 30 counties in Chongqing in 2011.Forty children aged 8-10of 1 randomly selected school from every county chosen were enrolled in the study.Thyroid volume of children was examined by B-ultrasonograghy.Body height and body weight were measured.The relationship between gender,age,height and weight and thyroid volume was analyzed,respectively.Results One thousand three hundred and twenty-two children aged 8-10 were investigated.The median of thyroid volume was 3.53 ml.The goiter rate was 5.52％ (73/1322).Thyroid volume of female and male was 3.55 and 3.51 ml,respectively.There was no significant difference of thyroid volume between female and male (H =0.68,P ＞ 0.05).Thyroid volume of children aged 8,9 and 10 was 3.30,3.53 and 3.76 ml,respectively.There was a significant difference of thyroid volume among different age groups(H =52.49,P ＜ 0.01).Thyroid volume of children height (110-,120-,130-and ≥140 cm,respectively) was 2.96,3.22,3.59 and 4.13 ml.There was a significant difference of thyroid volume among different height groups (H =149.23,P ＜ 0.01).Thyroid volume of children weight(17-,20-,30-and ≥40 kg,respectively) was 2.71,3.31,3.91 and 4.74 ml.There was a significant difference of thyroid volume among different weight groups(H =138.44,P ＜ 0.01).For the coefficients of simple and partial correlation,there was a significant correlation between thyroid volume and age,height and weight (P ＜ 0.05).The Spearman coefficient was 0.2411,0.3950 and 0.4285,respectively.The partial correlation coefficient was 0.0640,0.1154 and 0.2319,respectively.The standard partial coefficient of age,height and weight was 0.640,0.1154 and 0.3410,respectively.The proportion of the standard partial coefficients was 1 ∶ 1.8 ∶ 5.3.The function of body weight to thyroid volume was 5.3 times that of age and 3.0 times that of body height.Conclusions The goiter rate of schoolchildren in Chongqing is relatively high.Thyroid volume is affected by age,body height and body weight.The relationship between thyroid volume and iodine nutrition needs further study.

OBJECTIVETo explore the mechanism of male reproductive toxicity induced by acrylonitrile (ACN).

METHODSMale Sprague-Dawley rats were daily administrated ACN by intraperitoneal injection 5 times a week for 13 weeks at the dose of 0, 7.5, 15.0 and 30.0 mg/kg body weight, respectively. The rats were sacrificed and testes were removed at the end of 4, 8, 13 or 15 weeks, respectively. The activities of glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) and glutathione S-transferase (GST) and the levels of glutathione (GSH) and malonaldehyde (MDA) were detected in testes.

RESULTSFollowing ACN treatment of 4 weeks, the levels of GSH in ACN 15.0 mg/kg and 30.0 mg/kg group were (7.44 +/- 0.77) mg/g pro and (6.95 +/- 0.77) mg/g pro respectively, and the activity of GSH-Px was (70.89 +/- 4.01) U/mg pro in 30.0 mg/kg group, all of which were significantly higher than the control group (P < 0.05, P < 0.01). After 8 weeks, the levels of GSH decreased to (2.50 +/- 0.94) mg/g pro in ACN 30.0 mg/kg group (P < 0.01); the activities of SOD increased to (102.08 +/- 16.08) NU/mg pro and (113.30 +/- 17.20) NU/mg pro in ACN 15.0 mg/kg and 30.0 mg/kg group (P < 0.01). After 13 weeks, the levels of GSH declined in ACN 15.0 mg/kg and 30.0 mg/kg group, and the activities of GST decreased in ACN 30.0 mg/kg group, and of GSH-Px decreased in both doses group. However, the level of MDA [(0.68 +/- 0.16) nmol/mg pro] were significantly higher in 30.0 mg/kg group than that in control group [(0.38 +/- 0.12) nmol/mg pro] (P < 0.01). 2 weeks after stopping ACN treatment, the level of GSH restored to normal but the levels of MDA or the activity of GSH-Px in 30.0 mg/kg group were still higher or lower respectively than those of control (P < 0.05).

CONCLUSIONACN may impair the balance of antioxidant system, thus induce lipid peroxidation damage to rat testes.
